Hi Ziggy, if you hear a loud click** when the arm is expected to
lower, then it is just dried lube on the mechanism. Fairly straight
forward for the mechanically minded requiring partial strip and
re-applying a good quality lube such as singer oil - there are lots
of posts on this common issue to help you, although people are always
willing to offer advice here!
I would highly recommend you download the service manual and
follow the set up procedures to get the best out of the turntable.
New belts and other kits / parts are available from member Dillen.
***Sorry I should say if there is no click it could still be due to a bad case of dried lube....
